Higher-Order Topological Phase in the Two-Dimensional Type-IV Magnet MgCrO
Xiaorong Zou, Hyeon Suk Shin, Yanmei Zang +4
Type-IV two-dimensional (2D) magnetism-a newly classified collinear magnetic phase featuring nonrelativistic spin degeneracy and spin-orbit-coupling-induced momentum-dependent spin…
Accelerated Discovery of Nitrogen-Coordinated Dual-Atom Hydrogen Evolution Reaction Electrocatalysts via Machine Learning Potentials
Yanmei Zang, Hyun Gyu Park, Gi Beom Sim +7
The hydrogen evolution reaction (HER) is central to sustainable hydrogen production, and nitrogen coordinated dual atom catalysts (DACs) offer a promising route to noble metal acti…
Floquet-Engineered Odd-Parity Altermagnetic Higher-Order Topology in a Two-Dimensional Antiferromagnet CrCH
Xiaorong Zou, Hyeon Suk Shin, Baibiao Huang +5
Periodic driving provides a platform to dynamically tailor quantum states of matter, yet its impact on symmetry-protected topological phases remains incompletely understood. Here,…
Second-order topology in two-dimensional azulenoid kekulene carbon lattices
Xiaorong Zou, Hyeon Suk Shin, Chang-Jong Kang +5
The discovery of higher-order topological insulator (HOTI) has established a new paradigm for understanding symmetry-constrained boundary electronic states. Here, based on first-pr…
Stochastic Loop Corrections to Belief Propagation for Tensor Network Contraction
Gi Beom Sim, Tae Hyeon Park, Kwang S. Kim +6
Tensor network contraction is a fundamental computational challenge underlying quantum many-body physics, statistical mechanics, and machine learning. Belief propagation (BP) provi…
